Normally a threearm clutch should give better grip but these are all China clutches and it's always a lucky punch to have one that works got.

Thanks. Yeah there's a 3 arm on there now. Hoping the rear sprocket change makes a difference to it, as it's not impressive right now for grip...but I've found when something isn't geared right, that's kind of normal as you're asking a lot out of the clutch at that stage.

CAM2, I didn't build this motor, the long block was already assembled. I don't have a gasket set on hand, it takes 6 weeks plus for me to import this stuff in, usually I order it off Ebay or ali, as I live in New Zealand and parts aren't available locally. In this case, I'm leaving this motor alone as it currently goes and with our race in a weeks time...I don't want it not going<img src="https://www.pocketbikeplanet.com/images/smilies/smile.gif" border="0" alt="" title="Smile" class="inlineimg" />

However - I have 3 other motors already complete and 5 cylinders with pistons in a box that came with the bikes, so the next build I do will be from scratch. I'll strip the next motor down, replace all the bearings with those recomend by Chrisi and set the squish etc.

I'll certainly post build pics to share when I get stuck into it. I'm thinking of this as a base for the next build<img src="https://www.pocketbikeplanet.com/images/smilies/smile.gif" border="0" alt="" title="Smile" class="inlineimg" />

The reason why I ask is because those engines don't run too well on anything less than like 15:1 compression and not to mention whether you built it or not a leakdown test is warranted throughout the lifespan of the engine to detect unsuspecting airleaks...

Thanks CAM2 I did buy a leak down tester from your previous advise when I built the cag motor. So I will give it a go.

Testing squish is easy enough too, I was just panicking as I had 3 trikes here yesterday as needing small repairs done. I got them sorted quickly which was a relief.

Going online is my relaxing time, I helps me focus for the next project. Really appreciate all the good advise I get on here.

I've re geared the rear end, from 68 to 78 rear sprocket now. Too late at night to annoy my neighbors...so untested. But should be like once trying to start a car off in third gear...to now putting it in first.

Judging by the setup the 78 will barely be enough.....You can always go down to a 6tth pinion....With locked solid rear axles as you already know has alot of friction requiring the gearing starting in the 13-14:1 ratio area..........

Holy﻿-﻿moly, if you look in the dictionary for the phrase "world of difference" you'll see a picture of this trike with it's new rear sprocket! This thing screams!!!! Fried the tyres/sleeves and revved to max just like that! So cool...﻿﻿
